Im getting this error
java.lang.NumberFormatException: Invalid double: "-20.528899,"
im using a webservice to get latitude and longitude from bd, and show in a map.
I am not able to pass the latitude and longitude values to list
i am saving lat and long at the same column in db, so this field should be "lat, long" eg "-20.528899, -47.438933" and i need to parse this in the list...can i do this?

can anyone help me pls?
Change the following line in your setPosicao(String) method
String[] pos = posicao.split(" ");
INTO
String[] pos = posicao.split(", ");
(Since you have a ',' and a ' ' in the string)

We insert a point cloud in Revit and have to move and rotate it in several axles to get a good world alignment. We then need to apply the same transforms to a Revit MEP link that contains edgwise piping.
I have acquired the 3x4 matrix from the point cloud in revit, I would like to apply that to the revit mep link so that they are in alignment.
I have successfully applied the translation portion of the transform, I am stuck on the rotation portion. Could someone please assist with this. Dyslexia and Matrices do not work well together.
Thanks to Jeremy at the Building Coder for getting me this far!
9/4/19 - I edited the rotational part of the code, however the "ElementTransformUtils.RotateElement" does not have any effect on the link in Revit.

I had written a program to fetch all attributes from active directory based on username. now i want to get list of email address based on the group name CN= App_abc_Admin inside memerOf attribute.

while (result.hasMore()) {

String temp = attrs.get("samaccountname").toString();

In the above example i'm passing the search by and search term. But how to get list of users based on the CN in the memberOf attribute?
I tried to update the filter as below but no output
private String baseFilter = "(&(objectClass=Person)(memberOf=cn=App_abc_Admin,ou=Application Groups,dc=abc,dc=com))";
updated the filter as below.It works now
private String baseFilter = "(&((&(objectCategory=Person)(objectClass=User)(mail=*abc.com)(memberOf=CN=App_abc_Admin,OU=Application Groups,OU=Security Groups,OU=Users_OU,DC=abc,DC=com))))";
I've found one totally working query, which gets columns and their data from Oracle DB and puts the output in console printout.
I've spent 3 hours trying to display this data in Swing JTable.
When I am trying to bind data with JTable:
jTable1.setModel(new javax.swing.table.DefaultTableModel(
data, header
));
it keeps telling me that constructor is invalid. That's true, because I need arrays [] and [][] to make that. Any ideas how this can be implemented?
Here is the original query:
package com.javacoderanch.example.sql;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;

private static final String PASSWORD = "XXX";
public static void main(String[] args) throws Exception {

try {
//
// As the usual ritual, load the driver class and get connection
// from database.
//
Class.forName(DRIVER);
connection = DriverManager.getConnection(URL, USERNAME, PASSWORD);
//
// In the statement below we'll select all records from users table
// and then try to find all the columns it has.
//
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("select *\n"
+ "from booking\n"
+ "where TRACKING_NUMBER = 1000001741");
//
// The ResultSetMetaData is where all metadata related information
// for a result set is stored.
//
ResultSetMetaData metadata = resultSet.getMetaData();
int columnCount = metadata.getColumnCount();
//
// To get the column names we do a loop for a number of column count
// returned above. And please remember a JDBC operation is 1-indexed
// so every index begin from 1 not 0 as in array.
//
ArrayList<String> columns = new ArrayList<String>();
for (int i = 1; i < columnCount; i++) {
String columnName = metadata.getColumnName(i);
columns.add(columnName);
}
//
// Later we use the collected column names to get the value of the
// column it self.
//
while (resultSet.next()) {
for (String columnName : columns) {
String value = resultSet.getString(columnName);
System.out.println(columnName + " = " + value);
}
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
connection.close();
}
}
}

Above is the InsertInDB() method given,
It has a InsertPS PreparedStatement Object.
Here is it necessary to use clearParameters() method even though i am closing the InsertPS object at the end of the method.
(I have provided a separate method to close the connection object)
also another question: Is it a good idea to create PreparedStatement Object's outside any method within a class,initializing using Constructor and Say for example Once all Object's (each in different method) are used, close all PreparedStatement Objects using a separate method.

Suggestion's or Criticism on other aspects of code are also welcome.
For the first question, when you call:
con.prepareStatement()
a new preparedStatement is created, then parameters dont survive, i mean you dont need to clear then.
About the second question, in your implementation i cant see where you close your preparedStatement, and if you only add close, next time method will fail. Then, it is usual to create the preparedStatement and close it in the same method.
I know this may be stupid question i am gonna put here since i am a complete java noob. may be you guys can help me out to get this problem solved.
I am working on an application where a user would need the result dislayed on jsp page in pdf form, and the pdf is being generated as output stream in HTTP request, means when a user clicks on a button(on jsp) to generate PDF with result i.e. PDF getting generated on fly and sent to client browser.
